short_description: Roll back the running or startup configuration from a remote
|
|
server on devices running Lenovo CNOS
|
|
description:
|
|
- This module allows you to work with switch configurations. It provides a
|
|
way to roll back configurations of a switch from a remote server. This is
|
|
achieved by using startup or running configurations of the target device
|
|
that were previously backed up to a remote server using FTP, SFTP, TFTP,
|
|
or SCP. The first step is to create a directory from where the remote
|
|
server can be reached. The next step is to provide the full file path of
|
|
he backup configuration's location. Authentication details required by the
|
|
remote server must be provided as well.
|
|
By default, this method overwrites the switch's configuration file with
|
|
the newly downloaded file. This module uses SSH to manage network device
|
|
configuration. The results of the operation will be placed in a directory
|
|
named 'results' that must be created by the user in their local directory
|
|
to where the playbook is run.
